Definitions

  • one common fitting includes a connector body with an internally threaded compression nut screwed on to body of a fitting which has external male threads.
  • the end portion of a tube is slidably received within the compression fitting, and a worker must tighten the compression nut to compress a steel gland ring pre-installed between a compression fitting body and compression nut to secure the tube within the fitting.
  • workers can over-tighten some compression nuts to strip both female and male threads of a compression fitting this usually leave tube not secured or not locked in the position of a compression fitting.
  • the worker can under-tighten the a compression nut to the male threads of a compression fitting, thereby allowing the tube to become disconnected over time and expose the wiring unsecured within the tube.
  • FIG. 6 is a cross-sectional view of the tube engaging tapered, annular locking wedge of FIG. 5 taken along line 6-6 of FIG. 5.
  • FIG. 7 is an exploded, isometric view of a tube engaging tapered, annular locking wedge in accordance with an alternative embodiment of the present invention showing a possible resilient ring operably secured thereto.
  • FIG. 13 is an isometric view of an alternative possible base with two opposed collars in accordance with an embodiment of the present invention.
  • FIG. 17 is an isometric view of the tapered portion of the connector body of the annular connector body of FIG. 14.
  • FIG. 19 is a cross-sectional view of the quick lock fitting of FIG. 18, showing a possible attached position of the tube (shown in broken lines) in the quick lock fitting in accordance with an embodiment of the present invention.
  • FIG. 23 is an isometric view of an alternative possible configuration of three quick lock fittings of FIG. 1 on a T-shaped member.
  • FIG. 24 is an isometric view of a possible configuration of two different sized quick lock connectors of FIG. 1 on a threaded rigid coupling.
  • the connector body 46 defines a housing that encircles the end of the tube 42 and provides a chamber 79 for receiving the other components of the connector 44 therein.
  • the tube 42 preferably has a circular cross-section, and the opening 48 in the connector body 46 is circular to slidably receive the end of the tube 42 therethrough.
  • the connector body 46 includes a base engaging portion 80 opposite the opening 48.
  • the base engaging portion 80 includes attachment features for securing the body 46 to the base structure 70 such as by compression, pressing, rolling, riveting or the like.
  • a shoulder 82 may also be provided in the base engaging portion 80 for operably receiving and engaging the guide ring 60 therein and connecting to the base structure 70.
  • the tapered locking wedge 52 is formed of resilient material such as rubber, plastic or the like, and has a tapered exterior surface 90 and has plurality of spaced apart roller bearings, that are preferably substantially spherical balls and preferably made of steel, that operably engage and mate with the tapered interior surface 50 of the connector body 46 (FIGS. 14 & 15)
  • a through opening 92 extends through the tapered locking wedge 52 to define an annular locking wedge wall 94.
  • the opening 92 is sized to receive the end of the tube 42 as it is slid through the opening 92.
  • a plurality of spaced apart protrusions 1 12 or tabs extend from the ring 60 towards the opening 1 0.
  • the protrusions 1 12 are angled away from the opening 48 in the connector body 46 so that they allow the tube 42 to be inserted through the ring opening 110 and grasp the tube 42 should it be moved in a perpendicular direction away from the opening in the connector body 46.
  • Preferably at least 4 to 12 protrusions 112 are spaced equal distance around the circumference of the guide ring 60 as shown.
  • the base structure 70 includes a connector body engaging portion 120 and an object engaging portion 22.
  • a shoulder 82 of the base structure 70 is operably secured to the base engaging portion 80 of the connector body 46 thereby holding the tapered locking wedge 52 and guide ring 60 in place within the chamber 79.
  • the tube stop 123 (FIG. 12) on the base structure 70 is formed by dies to receive the end of tube 42 after tube 42 pass through guiding ring 60 the tube stop 123 stops the end of tube 42 from being inserted any further into the connector.
  • the tube 42 can be T-shaped 71 (FIG. 23), U-shaped, or elbow shaped.
  • a connection coupling 180 having different diameters on each end can be used to joint two different sized connectors 44 together as best shown in FIG. 24.
  • An installer can mount a threaded tube 42' to a connector 44 by first inserting the annular insert 302 into the connector 44 and then threading the threads 310 of the tube 42' into the annular insert 302 in the connector 44.
  • the installer can first thread the annular insert 302 onto an end of the threaded tube 42' and then insert the threaded tube 42' with the annual insert 302 installed into a connector 44.
